Touch Trace Timing Recording for Audio-Visual Synchronization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current electronic devices lack a mechanism to automatically relate recorded audio files to touch traces on graphic or video files, requiring manual connection and playback synchronization.
Innovation Solution
A system and method for recording and playing back touch information timing, which includes receiving touch point information, determining if it's a trace beginning point, and recording the corresponding timing, allowing for automatic synchronization of audio and visual playback based on recorded touch traces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If manual connection method is used to link audio files to graphic/video files, then users can connect the files by their own memory, but the process is time-consuming and lacks automation
Solution Approach 1:
The system performs preliminary action by automatically recording and storing the timing information when touch points are created on the graphic/video file during the recording phase. This pre-established timing data enables automatic synchronization during playback without requiring manual intervention, thus resolving the contradiction between automation and time consumption.
2Extent of automation
If no timing record is kept for touch traces, then the system structure remains simple, but automatic synchronization between audio and visual content cannot be achieved
Solution Approach 1:
The patent introduces timing information as an intermediary element that mediates between the touch trace data and the audio file. By recording the timing when each touch point is created and storing it in a data table, the system enables automatic synchronization without requiring complex direct linkage mechanisms, thus resolving the contradiction between automation and device complexity.
3Reliability
If touch trace timing is not recorded, then the data structure remains simple, but the relationship between touch actions and audio playback cannot be established
Solution Approach 1:
The patent segments the touch trace data into discrete touch points, each with its own timing information. By dividing the continuous touch trace into individual touch points and recording timing for each, the system establishes precise relationships between touch actions and audio playback without requiring complex continuous data structures, thus resolving the contradiction between reliability and device complexity.

AI summary
The present invention provides a recording method of touch information timing. The method comprises receiving a first touch point information, determining whether the first touch point is the beginning point of a trace; and recording a first timing with respect to the receiving of the first touch point information if the first touch point is the beginning point of the trace.
